CECS 524 Program 1 Due Feb 6, 2023 2PM Problem: You are to create a C++ class for performing some basic statistics on a data set of integers. The data set must have at least one element and up to 100,000,000. The statistics to be computed are
  • mean of the data set,
  • minimum value of the data set,
  • maximum value of the data set,
  • sample variance of the data set,
  • sample standard deviation of the data set,
  • and the median value of the data set.
All data of the data set must be held in memory in an array. The array size is to be entered from the keyboard as the program runs. The program must check that the value entered falls between 1 and 100,000,000, inclusive. The program must read the name of the file containing the data set from the keyboard. And the program must ask the user if they want the data set printed as table. If yes then the data is printed in rows of 10 with width 8. Any other response is assumed as \"no\" and the data set prints in one column with width 8. If the user selects to output in table format, print a row of 80 \'=\' before the first row and after the last row. The DataSet class produces output only in PrintAll(bool table) and LoadData(std::ifstream &in);. See the class declaration on the last page of this document. You MUST use C++ and you MUST use the class declaration in this document. You may not alter the class declaration in any way. Submit to the Dropbox for Unit 1 your C++ class and a main function that creates and executes an instance of the DataSet class to produce the output on the next pages. DO NOT ZIP, RAR OR COMPRESS THE FILES IN ANY WAY. MAC USERS DO NOT SUBMIT ZIP FILES OR YOU WILL GET ZERO FOR THE ASSIGNMENT. Sample run in table format. This program calculates several basic statistics for a data set of integers of any size > 0 && 100,000,000 Enter file name:data.txt Enter an integer number at least as big as the data set:89789 Do you want to print the data set in a table(Y/N):y Data set size = 28

39 45 45 51 54 65 67 67 67 74
78 78 88 91 95 98 99 100
mean = 55.1786 min = 9 max = 100 sample variance = 828.7447 sample standard deviation = 28.7879 median = 52.5000 Output complete Sample run in column format. This program calculates several basic statistics for a data set of integers of any size > 0 && 100,000,000 Enter file name:data.txt Enter an integer number at least as big as the data set:67 Do you want to print the data set in a table(Y/N):n Data set size = 28 9 12 20 22 23 23 30 34 34 37 39 45 45 51 54 65 67 67 67 74 78 78 88 91 95 98 99 100 max = 100 sample variance = 828.7447 sample standard deviation = 28.7879 median = 52.5000 Output complete The DataSet class declaration. You may not change anything about it or add anything to it. /*************************************************************** * class DataSet performs basic statistics on a data set of * * integers.
